Abstract

Piezoelectric materials attract intensive attention from the automotive to health industries for such applications as sensors, actuators, and transducers due to their ability to convert mechanical energy to electrical energy and also, as a reversible effect, electrical energy to mechanical energy. Since eco-friendly and renewable energy generation has gained crucial importance, piezoelectric materials offer ideal solutions in many fields. The improvements in nanomaterials and characterization techniques also offer the possibility of creating novel approaches for researchers. Along with the rising environmental awareness in recent years, studies on developing alternative materials to Pb containing compositions with similar superior properties present important outputs. In this context, this study aims to produce light and flexible composites with superior characteristics by synthesizing boron (B3+) doped 0,94(Bi0,5Na0,5)TiO3-0,06BaTiO3 BNT-6BT piezoceramics, which offer similar structure and properties as the most commonly used Pb-containing Lead zirconate titanate (PZT) ceramics, and used in polyvinylidene fluoride (PVDF) polymers. Characterization of the piezoceramic powders synthesized by hydrothermal method was performed using x-ray diffraction (XRD) and scanning electron microscopy (SEM-EDX) analyses. After the addition of the piezoceramic powders into PVDF polymer as filler material, fiber structure was obtained using the electrospinning method. The morphology of the fibers was investigated using SEM-EDX techniques, while a detailed analysis as Fourier-transform infrared spectroscopy (FT-IR) was used for observing the alteration in β phase, which provides the piezoelectric properties. The obtained results indicate that substantial improvements in the piezoelectric properties were observed by adding boron-doped piezoceramics into the PVDF polymers.

Özet

Piezoelektrik malzemeler, mekanik enerjiyi elektrik enerjisine ve tersinir olarak da elektrik enerjisini mekanik enerjiye dönüştürme kabiliyetleri sayesinde otomotivden sağlığa kadar pek çok sektörde; sensör, aktüatör ve transdüser gibi uygulamalar için yoğun ilgi görmektedir. Çevreci ve yenilenebilir enerji üretiminin büyük önem kazandığı günümüzde, yeni geliştirilen piezoelektrik malzemeler pek çok alanda ideal çözümler sunmaktadırlar. Nanomalzemeler ve karakterizasyon tekniklerinde yaşanan ilerlemeler de araştırmacılara yenilikçi yaklaşımlar geliştirme imkânları sunmaktadır. Son yıllarda artan çevre duyarlılığı ile birlikte Pb içerikli malzeme kompozisyonlarına alternatif benzer üstün özellikli malzeme geliştirilmesi araştırmaları önemli çıktılar ortaya koymuştur. Bu çerçevede bu çalışmada, en yaygın kullanılan Pb içerikli kurşun zirkonat titanat (PZT) seramiklere benzer yapı ve özellikler sunan 0,94(Bi0,5Na0,5)TiO3-0,06BaTiO3 BNT-6BT piezoseramiklerin bor (B+3) katkılı tozlarının üretimi ve bu tozların poliviniliden florür (PVDF) polimerinde kullanımı ile üstün özellikli hafif ve esnek kompozitlerin üretimi amaçlanmıştır. Hidrotermal yöntemle üretilen piezoseramik tozların karakterizasyonu x-ışını difraksyonu (XRD) ve taramalı elektron mikroskobu (SEM-EDX) analizleri ile gerçekleştirilmiştir. Piezoseramik tozlar, PVDF polimerine katkı maddesi olarak eklendikten sonra elektroeğirme yöntemiyle fiber yapılar oluşturulmuştur. Fiberlerin morfolojisi SEM-EDX teknikleri, piezoelektrik özellikleri sağlayan β fazındaki değişim ise Fourier dönüşümlü kızılötesi spektroskopisi (FT-IR) gibi detaylı analizlerle incelenmiştir. Elde edilen sonuçlar, bor katkılı piezoseramik tozların PVDF polimerine eklenmesiyle piezoelektrik özelliklerde iyileşmeler sağlandığını göstermektedir.
